12 Correct handling at Coating Thickness Measurement with exter-
nal sensors
Sensor
Spring shaft for handling
Measurement head
The sensor has to be touched at the lower pole segment and it has to be pressed
slightly onto the test object.
The black chequered pole segment is movably seated on a spring. By means of the
spring, the sensor tip presses onto the test object with a defined force. This way,
measurement errors can be avoided.
It is recommended to perform several test measurements before the first use of the
instrument. In this way, further measurement errors can be avoided.
13 Trouble shooting
13.1 The instrument should always be calibrated on the uncoated base material to be
measured instead of the base plate included in the delivery. Like this, accuracy is
more precise from the beginning.
13.2 Sensors will eventually wear off. Life of the sensor will depend on the number of
measurements taken and how abrasive the coating is. Replacement of a sensor
should only be performed by qualified staff.
14 Restore factory settings
14.1 In the following cases it is recommended to restore factory settings:
- The instrument does not measure any more.
- Measurement accuracy is degraded caused by the abraded sensor or affected by
environmental conditions.
- After the replacement of a new sensor.
14.2 Procedure:
To restore factory settings includes both, setting of "Fe" (F) and of "NFe" (N).
It can be only performed one after another. The procedure is as follows:
14.2.1 It is always differentiated between the symbols „Fe" and „NFe". If „Fe" is dis-
played, factory settings will be done for „Fe" type, and if „NFe" is displayed, it will be
done for „NFe" type.
